Evolution Rotation Lab
Station 1: Homologous and Analogous Structures
1. Which structures are analogous to one another?
2. Describe how the internal structures are similar.
3. Which structures are homologous to one another?
4. How can different organisms have similar internal anatomy even though most of the structures do not
perform the same function?
Station 2: Embryology
1. Hypothesize which embryo is from each of the following
organisms to the right:
Species
Embryo
Human
Chicken
Rabbit
Tortoise
2. Hypothesize which embryo is from each of the following
organisms:
Salamander
Fish
Species
Human
Embryo
Chicken
Rabbit
Tortoise
Salamander
Fish
3. Describe how the embryos changed for each of these organisms from their earliest to latest stages.
Species
Anatomical Changes From Early to Late Stages
Human
Chicken
Rabbit
Tortoise
Salamander
Fish
4. Look again at the six embryos in their earliest stages. Describe the patterns you see. What physical
similarities exist between each of the embryos?
5. Does this suggest an evolutionary relationship? Explain how these embryos can be used as evidence of
a common ancestor between each of these six organisms.
Station 3: Cell Phone Evolution
1. Put the cell phones in order of earliest to most recent phones.
2. This is man-made evolution; how is this different than evolution in nature?
3. Which cell phone is the most complex? ___________
4. Which cell phone is the most simple? ____________
Station 4: Biogeography
1. How could island-dwelling organisms be unique to an island, similar yet different to nearby mainland
organisms, and not have the same adaptations as other organisms living in similar island habitats?
Station 5: Fossil Record
1. Which layer is the oldest? How do you know?
2. What do the organisms in the layers represent?
3. Write an explanation that summarizes the change in layers and fossilized remains of organisms.
